Fluid Level Vessels - Physics Demonstrations - Fluid Level Vessels | Physics Undergraduate Labs

Purpose

Connected vessels of different shapes show that static fluid level depends only on depth, not container geometry. Demonstrates the hydrostatic paradox: containers with vastly different fluid masses exert the same pressure at equal depths.

Four connected glass vessels—narrow tube, Erlenmeyer flask, funnel, and beaker—mounted on a wooden base and connected by red tubing, all filled with red-colored water to the same height

Figure 1: Four vessels of different shapes connected at their bases show identical fluid levels, demonstrating that hydrostatic pressure depends only on depth.
